' Patented .rul i, 1908.

To all whom it mag concern:

Be it known that I, OTTO E. GOLDSOHMIDT,

of the city of Montclair, .county of Essex, and

State 'of New Jersey, have invented certain new and useful Improvements in Apparatus for Handling Granular Material, of WhiClIfillG followin is a full, clear,an'd exact specifica tion, suc as .will enable others skilledin the art to which it appertains to make and use the same. I

My invention relates to an improvement in those apparatus for removing ashes and similar granular material by air pressure, and particularly to those apparatus in which the ashes are deposited first in a receiver'and subsequently drawn from the receiver into a cart or other means for disposing of the same.

The object of my invention is to provide means by which the flow of ashes from the receiver may be facilitated andito avoid the clogging of the outlet which wouldrender the air pressure'insuflicient to start the move ment of the ashes. To this end I provide the outlet of the receiver with a nozzle communlcating with the outer air which nozzle acts as an lnspirator to allow the initial flow of the air and to start the movement of the ashes.

T also prefer to combine with this nozzle or inspirator a peculiarly arranged shaker by w h1ch the ash may be agitated during the inception of the operation.

- The invention involves various other features and all will be fully set forth hereinafter and be particularly pointed outin the claims. Reference is bad to the accompanying drawlngs, which illustrate, as an example, one manner of embodying my invention.

Figurel is a side view of the ash or other receiver with parts in section showing the invention; Fig. 2 is a horizontal detail'section onthe line 2 2 of 1; and Fig. is an outline view ofthe entire system.

In Fig. 8 a typical system isshown in outline inwhich system the parts are arranged to remove the ashes from a boiler room to the side 'walk'in a cart provided for the reception of the ashes. In this view, 10 indicates the boller, 11 the blower and a the receiver. 12 Indicates a cart on the street -Wl'liCl1 is charged with ashes. As will be fully understood from the prior art the blower 11 ,creates a suct on or partial vacuum in the 'PIPB line b WhJCh communicates with the rece1ver a and cart 12. The suction lines b establish communication between the receiver a and cart 12 and also between the cillating the pipe section a.

boiler as at '16. So that theashes may be drawn from any or all of these points. The various pipelines are provided with valves 'or gates to control them and when it is desired to fill the receiver a, the suction 00nnec-' tion I) is'cut oif fromthe cart 12 so that the suction created inthe pipe line b will. exert itself in the receiver 11 causing ashes to be turned in to said receiver from the various points 14, 15, or 16 or any of them. When it is desired to charge the cart 12 from the receiver, a the suction line b is opened into 7 communication with the cart 12 and its communication with the receiver a is, closed with the result that the suction is exerted in the cart 12 and pipe line 6 connecting the cart with the receiver a, the ashes being then receiver and boiler ash pit as at. 14. the soot chamber as at 15- and the floor in front of the drawn through this pipeline from the receiver to the cart. The foregoing it will be understood, is simply an example of one of the various systems in which my invention may be employed. Referring particularly to Figs. 1 and 2, the lower end of the receiver is preferably tapered as at a and fitted therein is a-rotatable pipe section 0 having handles 0 which facilitate manually rocking the section back and forth. The section 0 has connection with the discharge pipe (1 and is preferably rovided on its interior as shown best in i 2 with ribs 0 which serve eflectually to agltate the ashes lying in the pipe section. e'indicat es the nozzle which is in the form of an elbow the outer end of which communicates with the atmosphere and the inner end of which is turned down- This nozzle e is refinto the pipe section 0. erably' provided on its exterior with ri s e which assist in the agitatin action.

In the operation of this evice upon bringing about a partial vacuum'in the pipe (I the atmospheric pressure forces itself through the 1,60

the tapered lower-end ofthe ashpit 14 and the invention of course is not limited to the point of application.

When t e inspirator nozzle and the-rotatable ipe section are applied to the ash-pit, the admission of the air through the inspirator nozzle prevents a diminution of the draft which passes through vthe grates of by fluid ressure and also having an inspira- -tor nozz e communicating with the exterior of the receiver and opening into the outlet. I

2. A receiver having an outlet throughwhich its contents are adapted to be forced by fluid ressure and also having an inspirator nozz e communicating with the exterior of the receiver and opening into the outlet,

and a movable wall juxtaposed to the nozzle outlet for the purpose specified.

3. A receiver having an outlet through -wl1ich its contents-.are adapted to beiorced:

by fluid ressure and also having an inspiratornozz e communicating with the exterior of the receiver and opening into the outlet, and a'rotatable ipe section surrounding the nozzle outlet and adapted to be oscillated for the purpose specified.

4. A receiver having an outlet through which its contents are adapted to be forced,

by fluid 'ressure and also having an inspira tor nozz e communicating with vthe exterior of the receiver and opening into the outlet, and a rotatable ipe section surrounding the nozzle outlet and ada ted to be oscillated for the pur ose specifie said nozzleand' pipe section having exterior and interior ribs respectively for the' purpose specified,

5. A receiver having an outlet through which its contents are adapted to be forced by fluid'pressure and a rotatable pipe section in said outlet adapted to be oscillated for the,

purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
